Fortified structure with an L-plan and two floors, one of which is a basement, it was planned and built by the Austrians in 1860 on a rocky spur in a strategic position to defend the access to Valle di Sole and Trentino along the border of Tonale. Of great strategic importance, at the end of World War I it was abandoned and partly destroyed by the activity of the so-called "recuperanti", that is people who used to collect war surplus.
The fort has been recently renovated by the municipal administration of Vermiglio and by the provincial offices of Trentino.
The fort houses a permanent exhibit on the "White War". It often houses cultural events like concerts, art exhibits, and theater performances.
